What is Water Hammer?
The noise from banging pipes is caused by shocks of high speed water flowing in the pipe when a fixture is suddenly closed. Sudden stoppage causes a “bounceback” of the water and is called water hammer. It might be compared to driving your car at slow speed into a wall where the effect is negligible. However, if you drove the car at a much higher speed, the impact would be greater, and consequently so would the bounceback or shock. Dishwashers, clothes washers, quick closing faucets all contribute to creating water hammer which is not only annoying but damaging to pipes and appliances.

The simple, economical solution is Watts No. 150A designed with a pre-charged air chamber and a rugged sealed-in diaphragm which flexes to absorb the shock. It can be installed vertically, horizontally or at any angle.
